方法一:修改取消按钮文字颜色及背景图片的代码片段，要放到代理方法中修改，否则遍历找不着呀，那就修改不了了
-(void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar
{
// 显示取消按钮
[searchBar setShowsCancelButton:YES animated:YES];
// 修改UISearchBar右侧的取消按钮文字颜色及背景图片
for (UIView *searchbuttons in [searchBar subviews]){
if ([searchbuttons isKindOfClass:[UIButton class]]) {
UIButton *cancelButton = (UIButton*)searchbuttons;
// 修改文字颜色
[cancelButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[cancelButton setTitleColor:[UIColor whiteColor] forState:UIControlStateHighlighted];
// 修改按钮背景
[cancelButton setBackgroundImage:[UIImage resizedImage:@"login_btn_login.png"] forState:UIControlStateNormal];
[cancelButton setBackgroundImage:nil forState:UIControlStateHighlighted];
}
}
}
对于用环信的搜索框,然并卵~用方法二轻松解决
方法二:在searchBar的懒加载中设置
- (UISearchBar *)searchBar
{
if (!_searchBar) {
_searchBar = [[EMSearchBar alloc] initWithFrame: CGRectMake(0, 0, self.view.frame.size.width, 44)];
_searchBar.delegate = self;
_searchBar.placeholder =@"请输入联系人";
[UIColor colorWithRed:0.747 green:0.756 blue:0.751 alpha:1.000];
[[UIBarButtonItem appearanceWhenContainedIn:[UISearchBar class], nil] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor blueColor],UITextAttributeTextColor,[NSValue valueWithUIOffset:UIOffsetMake(0, 1)],UITextAttributeTextShadowOffset,nil]forState:UIControlStateNormal];
}
return _searchBar;
}
